These are mostly treated as half-hardy annuals, though really perennial. The variety Heavenly Blue bears funnel-shaped, sky-blue flowers in summer. It may be grown as a pot plant in the greenhouse or planted outdoors in a warm, sunny position. A quick-growing climber, of twining habit, it may ultimately reach 15 ft. Seed is sown in heat in February, 2 seeds to a pot. Considerable confusion exists about the naming of ipomoeas, some authorities referring them to the genus pharbitis, others to convolvulus.
